Can anyone confirm whether the 2014 3 series Active Cruise Control includes the Stop & Go functionality?

According to the pinned post on the 2014 pricing, changes, etc:
"Active Cruise Control with Stop & Go (5DF), previously priced $2,400, is now available for $1,200."

However, the official ordering guide lists option 5DF as only "Active Cruise Control."

The current BMW Technology Guide makes a distinction between basic Active Cruise Control and that with Stop & Go. It does not list the 3 series as having Stop & Go. However, the website does not appear to have been updated for MY 2014 yet.

Question on its behavior:
If I am traveling at 80mph setting the seconds to the minimum and a car cuts in, does our car slow down gradually to increase the preset distance or is it braking harder than necessary?
2nd scenario to the above, after the other car cuts in and then brakes hard completely to a stop, would our car recognize the rapid closing in distance and apply maximum brake force?

If a car cuts in, it will slow to reestablish the necessary distance. For that reason, I don't use it in heavy traffic. It is perfect in light traffic. In the second case, the car will apply maximum braking. First, an icon appears in the head-up, then an alarm sounds, then brakes are applied. I haven't experienced the automatic braking in that situation but I have experienced the alarm. Collision Avoidance (I think that's what it's called) has a separate activation from cruise control. I have mine set so it is always on.

No!!! You are responsible for your car. You need to be able to control your car, understanding ABS and DSC. In an emergency situation, hit the brakes with full force and your car will manage stability. The automatic systems are for backup only. I think (but I don't know) that Collision Avoidance will add braking if you don't fully engage the brakes.
